Small waste incineration tail gas treatment system and treatment technology thereof

Abstract

The invention discloses a small waste incineration tail gas treatment system and a treatment technology thereof. A flue gas outlet of a waste incinerator is connected with an inlet of a secondary combustion chamber, an outlet of the secondary combustion chamber is connected with the inlet of a quench cooler; the outlet of the quench cooler is connected with the inlet of a heat exchanger; the heat exchanger preheats cold air and then blows fresh air into the waste incinerator through an induced draft fan; a flue gas subjected to heat exchange enters the inlet of a dust collector; the outlet of the dust collector is connected with the inlet of a deacidification tower; the outlet of the deacidification tower is connected with the inlet of a demister; the outlet of the demister is connected with the inlet of an adsorber; the outlet of the adsorber is connected with the inlet of a deodorizer; and a tail gas is purified through a biofilter and then connected with a chimney, the biofilter and the chimney can be arranged in parallel and the flue gas is finally discharged. According to the small waste incineration tail gas treatment system, a harmful flue gas generated through incineration passes through a tai gas purification system, the flue gas is deep purified, the purification efficiency is high, up-to-standard discharge can be achieved, and the small waste incineration tail gas treatment system is very suitable for a small household refuse innocent treatment work station.

Description

technical field [0001] The invention relates to a tail gas treatment system, in particular to a small waste incineration tail gas treatment system. The invention also relates to the treatment process of the small waste incineration tail gas treatment system. Background technique [0002] At present, the problem of domestic waste in remote rural areas has become the most urgent environmental problem to be solved, and it is becoming more and more difficult to solve domestic waste. Most of the domestic garbage of the villagers is directly burned in the open air without any follow-up treatment, which seriously affects the environmental safety and the living environment of the residents. Toxic and harmful gases and a large amount of dust produced by garbage burning will seriously affect the quality of the surrounding environment. Especially dioxins, SO 2 The harm is even greater and will directly endanger the physical and mental health of the people. Therefore, it is particul...
